Never liked the UTG bipods, always felt the exposed springs were kind of unrefined and chinzy. Another one I use, but a bit bulkier, is by CAA. Spring loaded deploy legs, indexed legs, and a rail under it's belly.

I've had good luck with their offerings. I like a Harris bipod but have tried others for .22 and they all work well on the smaller caliber rounds.
